Description

Technical Field

[0001] The invention relates to a core positioning structure of a power cable connector, belonging to the technical field of positioning tooling of power cable connectors. Background Art

[0002] The plug in the car power cable connector is inserted into the socket, and the two ends are located on both sides of the socket to form a plug and a connection end with the cable respectively. Since the insulating material used at the connection between the plug and the socket is easily softened and deformed by heat, the insulating material will be softened by heat when the plug is welded to the cable and when the connector is used. In addition, the twisting of the cable during welding and use will cause lateral stress on the plug, causing the plug to be skewed, deformed, eccentric, etc., and different plugs are not parallel, which will cause poor contact of the plug in the power cable connector during power-on operation, causing the plug to spark and the connector to burn. Summary of the invention

[0005] A further design of the above technical solution is as follows: a sleeve for connecting to a cable is provided at one end of the plug core located at the back of the socket, and the cable is inserted into the sleeve and welded to the sleeve.

[0006] A welding hole for welding is provided on one side of the sleeve.

The tail clip is fixed on the socket through the matching of the internal thread and the external thread.

[0010] The outer walls of the socket and the tail clip are both provided with knurling.

[0011] The support frame is made of metal material or polytetrafluoroethylene material.

[0012] Compared with the prior art, the utility model has the following advantages:

[0020] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0021] like Figure 1 and Figure 2 As shown, the plug positioning structure of the vehicle power cable connector of this embodiment is shown, wherein the power cable connector includes a socket 1, a plug 2 and a tail clip 3. The socket 1 includes a cylindrical shell and an insulating material arranged in the shell. Four plugs 2 are arranged on the insulating material. The plugs 2 penetrate the insulating material, thereby forming a plug 21 and a sleeve 22 for connecting with the cable 4 on the front and rear sides of the socket 1 respectively. The rear side end of the shell of the socket 1 is provided with an external thread, and the tail clip 3 is cylindrical. The front side end of the tail clip 3 is provided with an internal thread that matches the external thread of the socket 1, and is connected to the socket 1 through the thread, which is used to wrap and protect the sleeve 22 on the rear side of the socket 1 and the end of the cable 4.

[0022] Combination Figure 3 As shown, the inner diameter of the sleeve 22 of the ferrule 2 matches the diameter of the cable 4 , the end of the cable 4 is inserted into the sleeve 22 , a welding hole 23 is provided on the side of the sleeve 22 , the cable 4 can be exposed from the welding hole 23 , and the cable 4 and the sleeve 22 are welded through the welding hole 23 .

[0023] The positioning structure of this embodiment includes a support frame 5, and the support frame 5 is made of insulating and heat-resistant materials, such as Figure 4 As shown, the support frame 5 is cylindrical, and four positioning grooves 51 are evenly arranged along the circumferential direction on the outer periphery. The cross section of the positioning groove 51 is semicircular, and the diameter matches the diameter of the cable 4. When in use, the support frame 5 is placed between the four cables 4 and is set close to the sleeve 22. The four cables 4 are respectively embedded in the corresponding positioning grooves 51 to support the cables 4 to prevent the cables from twisting, so that the four cables 4 and the four ferrules 2 are respectively kept parallel to each other. Therefore, when the cables 4 and the sleeve 22 are welded, the cables 4 and the ferrules 2 will not be offset or skewed. After the connection is completed, wait for the temperature to drop, install the tail clip 3, and the cable 4 is restricted in the positioning groove 51 by the positioning groove 51 and the inner wall of the tail clip 3. The tail clip 3 wraps the sleeve 22, the end of the cable 4 and the support frame 5 for protection. When in use, the cable 4 will inevitably bend, etc. Since the cable 4 is restricted in the positioning groove 51, the end of the cable 4 will not bend or twist, and the ferrule 2 will not be caused to deviate or tilt. The four ferrules 2 are always parallel to each other and can be used normally without poor contact, causing the ferrule to spark, the connector to burn, and other problems. Embodiment 2

[0024] The core positioning structure of the power cable connector of this embodiment is basically the same as that of the first embodiment, except that: in this embodiment, two support frames 5 are provided, which are made of metal material and polytetrafluoroethylene material respectively.

[0025] When welding the cable 4 and the ferrule 2, a metal support frame 5 is used, and the diameter of the positioning groove 51 on the support frame 5 matches the outer diameter of the sleeve 22, such as Figure 5As shown, the support frame 5 is arranged between the four sleeves 22, the sleeve 22 is embedded in the positioning groove 51, the cable 4 is inserted into the sleeve, and the end of the cable 4 is also embedded in the positioning groove 51, the support frame 5 directly supports and positions the ferrule 2 to prevent the ferrule 2 from being offset or skewed during welding, and the metal support frame 5 can also withstand the high temperature during welding; after welding, when the temperature drops, the support frame 5 is taken out and replaced with a support frame 5 made of polytetrafluoroethylene. The diameter of the positioning groove 51 on the support frame 5 matches the outer diameter of the cable 4. The support frame 5 is arranged at the end of the cable 4 as in the first embodiment, and close to the ferrule 2. The support frame 5 does not contact the ferrule 2, and there will be no short circuit. Then the tail clip 3 is installed for normal use; this embodiment can also use a cable tie to fix the cable and the support frame 5 to prevent the support frame 5 from sliding.

[0026] In this embodiment, the outer walls of the socket 1 and the tail clip 3 are both provided with knurling, so as to facilitate the rotation of the socket 1 and the tail clip 3 for threaded connection.

[0027] The technical solutions of the present utility model are not limited to the above-mentioned embodiments, and all technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present utility model.
